Participants from the first cohort (SLAS I) were based in the South East of Singapore and participants from the second cohort (SLAS II) were based in the South Central of Singapore. SLAS I cohort was recruited in 2003, and SLAS II cohort was recruited between 2009 and 2013. Both cohorts were followed up every three to five years.
